Data are n/N (%) and RR (95% CI). Overall interaction terms were significant for cooperation rates only in the age subgroup: gender, p=0.31; age, p=0.015; education, p=0.32; location, p=0.11.
*P values obtained from an interaction term between intervention groups and demographic characteristic.
RR, risk ratio.
